BOTTLE-CAP OPENER.

Application filed March 4, 1915.

To all whom it may concern Be it known that I, GEORGE GILL, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Bottle-Cap Opener; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved botthe cap opener, and an object of the invention is the provision of a simple, efficient and practical device of this nature comprising improved features of construction, said opener being particularly designed for removing milk bottle caps.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings, Figure l is aview in perspective showing the bottle cap opener in a position about to be forced through the cap. Fig. 2 is a perspective view of the opener having been forced through the cap. Fig. 3 is a sectional view through Fig. 2.

Referring more especially to the drawings, 1 designates a fiat annular ring, from the periphery of which a shield shaped spear 2 projects, the edge portions of which are provided with cutting edges 3, there being a contracted neck a between the spear and the ring 1. It is to be noted that the spear has a partial twist, as shown, so that when the spear is forced through the bottle cap, a par- Specifioation of Letters Patent.

tial rotary movement is imparted to the entire opener, thereby assisting the shoulders 6 to assume positions under the bottle cap. After the spear 2 has entirely penetrated the bottle cap and by continuing this partial movement, the shoulders 6 will positively assume positions under the bottle cap, and then by an upward pull upon the ring 1 the cap will be removed. 1

The invention having been set forth, what is claimed as new and useful is A bottle cap opener comprising a body portion consisting of a flat ring, a spear having angularly disposed cutting edges, a contracted neck integrally connecting the ring and the spear, said spear having a horizontal upper surface forming shoulders upon opposite sides of the neck to engage under the bottle cap, said shoulders having spurs projecting upwardly to pieroe'the bottle cap, said spear having a spiral or screw twist, whereby when the spear is forced through the cap, a rotary movement is imparted to the opener sufliciently to carry the shoulders under the cap beyond the incision made by the spear, whereby the spurs may pierce the cap upwardly.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE GILL.
